Preface, I have a 2009 Honda Fit Sport, bought used last year from a reputable dealer. I'm clueless about car things, and had the same mechanic for 15 years. But he recently disappeared, so i had to go somewhere new, and fast, to get my insurance squared away this year.
So I went for a routine inspection at a local place (that has a 4.8 star rating, for what that's worth). This guy said my back tires were balding and would fail inspection, he heavily implied that if i got my tires done by someone else, that it would interfere with my obtaining an inspection in due time, or some such business. so i gave him 300 bucks and, despite feeling a little railroaded, was generally happy to have new tires.
Except after that, maybe a week later, my tire light kept on going on, it seemed like the back tires had a slow leak that i would have to refill once a week, which was discouraging. I put it off because the idea of confronting them made me feel anxious, but eventually i made my way back to them and found the courage to ask what went wrong.
They said the tpms valves (right word/term?) were causing a leak, but it wasn't their fault. I asked why they would both break at the same time as their tire change, they said they must have both been so corroded that any tire change would have broken them. They then said it would be 75 dollars each to fix. I must have really gaped at them because they then said, maybe they could fix them for less, they would have to look.
While bringing me back to my car, they showed me two random TPMS valves, one with a broken seal, and one with a hairline crack in the metal. He then said, you know, its where we live, these things are bound to happen. because we live in new england, things corrode ( i am not near a coast or anything, im in Blackstone, MA)
After i was driving away i realized i deeply wish i could have mentioned to them that i had my front two tires replaced just weeks before the back ones, and they are functioning perfectly, why would both the back be so fragile, and both the front be fine?
So, is corrosion a credible excuse? Is this a common occurrence?
